So before you start rattling off baseless ideas, do us a favour, open up your lcd, remove the fluorescent power connectors and then try to reply to this thread.

That would depend on which type of LCD you're talking about. You have reflective, transparent and transflective (a combination of the other two).

From what I understood, the Jetbook as a reflective screen. And from what I've seen, a picture frame has a transparent screen.
Reflective = no backlight, all light gets reflected on a kind of mirror behind the screen, so you'll need a lighted surrounding
Transparent = backlit, all light comes from the device as the screen is transparent to light. Surrounding light will not (or hardly noticable) be reflected back and thus you'll always need a backlight.
Transflective = backlit, there is a mirror behind the screen which will reflect surrounding light, but it is also transparent so backlight will also get through. The better PDA's will have a screen like this.

I agree, it works perfectly. I can read in bright sunlight without any problem on my PDA and it also works when I'm in a dark bedroom under the covers
